I am not able to place duplicate records in a separate file using SORT.
The JCL I am using is as follows:
Code:

//STEP04 EXEC PGM=SORT                           
//SORTIN DD DSN=ABC
//SORTOUT DD DSN=DEF
//SORTXSUM DD DSN=XYZ
//SYSIN DD *               
   SORT FIELDS=(5,18,CH,A)
   SUM FIELDS=NONE,XSUM   
/*   
//SYSOUT    DD SYSOUT=*

DFSORT does NOT support XSUM, but it can do the same thing with the SELECT operator of ICETOOL. The DFSORT/ICETOOL job would be:

Code:

//STEP04 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*                           
//SORTIN DD DSN=ABC
//SORTOUT DD DSN=DEF
//SORTXSUM DD DSN=XYZ
//TOOLIN DD *               
SELECT FROM(SORTIN) TO(SORTOUT) ON(5,18,CH) FIRST DISCARD(SORTXSUM)
/*
